First JavaScript Parameter with Default Value: Is It Possible?

You can use destructed array in this case.

Example

function multiply(firstParameterDefaultValue=10, secondParameterValue) {
   return firstParameterDefaultValue * secondParameterValue;
}
console.log("The result="+multiply(...[,10]));

To run the above program, you need to use the following command −

node fileName.js.

Here, my file name is demo173.js.

Output

This will produce the following output −

PS C:\Users\Amit\javascript-code> node demo173.js
The result=100
